Electroweak and QCD corrections to top-pair hadroproduction in association with heavy bosons

S. Frixione, V. Hirschi, D. Pagani +2

We compute the contribution of order ${\alpha }_S^2{\alpha }^2$ to the cross section of a top-antitop pair in association with at least one heavy Standard Model boson -- $Z$, $W^{\pm }$, and Higgs --…
